Sorry 'bout that... Hertz, Avis and National are considered the 'big three'.

be careful about driving in mexico. some strange things go on particularly along the border. also be very very sensitive about bringing any form of a weapon across the border, also lots of insurance because many in mexico have none.

We use rental companies a lot--like everytime we go on a driving trip. We probably rent about 6-8 times a year.

I have found that Hertz will let you use a debit card--have them run it as a credit. Remember, though, that most car companies will put a hold for the amount of the rental plus some "overage" just in case.

Make certain that you are getting unlimited miles. Always. Some companies only allow you a certain # of miles per day.

Ditto with the gas.. fill it up on your own before turning it in.

Are you a member of AAA? If so, they have some excellent discounts--"double discounts" per se. Example---$25 off a weekly rental in addition to their standard 10%. Check your website. If you're not a member, consider joining because the $$ you save in the rental will more than pay itself back in your discount. I think single membership is usually around $30 bucks, plus you can get all the perks of trip maps, area guides, etc.

Definitely carry your insurance card ( or a copy) while you are on vacation and using the rental.

You can also pay for an extra driver, if say, hubby is going along. But that usually runs a good bit, like $8-10 a day.
